To It whom, it may calmer/1 Be it known that we, Joux ll. GREGORY and\V.-\I:1.icn W. JAeksoN, both of the city of Columbus, county ofFranklin, and State of Ohio, and FREDERICK N. CONNET, of the city andcounty of Providence and State of Rhode Island, all citizens ol" theUnited States,have invented certain new and useful Improvements inAutomatic l lowdiegulators for Liquids and Gases, ol whieh the followingis a specification, reference being had. therein to thettC(J()l1l})t1,1l \'lll drawing. I

This invention relates to means whereby the velocity of certain liquidsor gases passing through a given aperture automatically controls thellow of certain other liquidsor gases.

The object of'the invention is to provide a device that will be operatedby the flow of liquids or gases through a given aperture, said flow tooperate a valve the movement of which valve in turn to operate one ormore gates to allow a proportional flow of other chemicals or gases.

Tl's device is more particularly designed to operate in connection witha city water supply where the water possesses ccrtainimpurities that areto be precipitated by means of chemicals deposited in the water for thatpurpose. These chemicals may be supplied lro'm any number of tanksdischarging into the water in quantities proportioned to the amount ofwater used, and this supply is governed automatically by the velocity ofthe in'llowin'g water. To accom lish this purpose, a chamber has beenpr0v1ded with a valve to control the inlet to said chamber, said valvebeing actuated by the force of the inllowing liquid to be raised andopened an amount in proportion to the pressure or velocity of the flow,and this valve in turn is arranged through suitable mechanism to controlthe opening and closing of the chemical supply gates.

' This invention is not confined to controlling the flow of chemicals bythe flow of liq uids, as by its use the flow of liquids may be made tocontrol the flow of gases, or the flow of gases may control the flow ofliquids, or again the flow of gases may control the flow of gases or acombination of gases and I liquids, any of which may be subsequently lmixed to ether in any predetermined proportions i? desired; broadlyspeaking, our invention covers the automatic controlling of the flow ofany gases or liquids'by the flow of other gases or liquids.

The invention consists of other novel fea- ,tures and partsandeOmbinationsOf the same'as will be fully described hereinafter andthen pointed out in the appended claims. A, practical embodiment of theinvention is represented in the accompanying draw-' ings, forming a partof this specification, in which similar characters of reference indicatecorresponding parts in all the views.

In the drawings: Figure 1is a side elevation of the device illustratingan operating arrangement of the mechanism with portions broken away tobetter illustrate the action of the same. Fig. 2+is a plan view of thedevice with the three chemical tanks removed, showing the chemical inletgates and the pipe connection from said gates to the mixing tank.

Although the device may be operated by the flow of anyliquids or gasesto control the flowof other liquids or gases, we will first describe thesame as being operated by the flow of Water through the main tube toautomatically control the flow of a plurality of diflerent chemicals allto be subsequently deposited into a common reservoir for'the purpose ofprecipitating the impuritics in the water.

Referring to the drawings at 1 is the main inlet pipe through which theWater flows to the mixing receptacle or reservoir 2.

At 3 is a valve chamber having its lower portion tapered to betterregulate the area of the inlet opening which opening is controlled bythe disk valve {1. This valve is preferably fixed toan upright stem 5and depends on gravity to close it, saidstem works vertically inbearings 6 and 7 "and extends out through the upper end of the chamber.As the water enters through the inlet pipe 1 it strikes against the diskvalve 4 which allows said Water to pass through the chamber and outthrough pipe 9 into the reservoir. A horizontal shaft 10 is mountedabove this chamber 3 to turn freely in bearings 11 and 12 and on thisshaft is fixed the sheave 13 to which. is secured a Wire 1'4 or otherflexible connection to the valve stem 5. Acounterbalanee weight 15 lalso acts on this sheaveto rotate the shaft when the valve 4 rises. At16 is a large cam also fixed on shaft 10, said cam being caused torotate by the movement of valve 4 and by the movement of this cam thegate 17 is opened and closed throu h the connection 18, arm 19 and lever20, and the height to which this gate may be raised is regulated byadjusting the connection in the slotted arm 19. When it is desired tooperate more than one gate from this cam the shaft 21 may be mounted inbearings 22 and 23 and to it may be secured any additional number ofarms to operate as many gates the same as arms 24 am] 25, see Fig. 2,operate the gates 26 and 27. At 28 'is a chemical tank located in anyconvenient place and arranged to deposit its contents into the mixingreservoir2 through the pipes 29 and 30, the quantity of the flow beingcontrolled by the movement ofthe gate 17. At 31 is a float in saidchemical tank which actuates the inlet valve 32 to automaticallymaintain a given head in said tank by controlling the inflow through theinlet pipe 33. Any desired number of these chemical tanks may be usedand operated by the mechanism shown and described.

When gas is forced through the main supply 1 its action on the valve 4is inuch the same as that of a liquid, and at such a time a head 8 isused to close the upper end of the chamber 3 to confine the llow to pipe9. In place of chemical tanks, gas receptacles may be used to supplygasesinstead of chemicals if desired, or a combination of gas andchemical receptacles to supply eitherone or both to be mixed together inany predetermined quantities or subsequently mixed with the gases orliquids in the reservoir 2.

The operation of the device may be further described as follows: Whenthere is no flow through the main supply pipe 1 the valve 4 falls by itsown gravity and rests upon its seat at the lower end of the taperedportion closing the inlet and when in this position the cam 16 isrotated to close the gate 17 to shut oil the auxiliary supply. When gasor liquids are allowed to flow through the main they strike theunderside of the valve disk 4 and raise it from its seat, the greaterthe velocity of the flow the higher the valve disk is carried, and owingto the tapered form of the chamber the area of the opening around thedisk gradually increases as the valve rises therefore as this disk isfree to be actuated by thellow it will be raised in direct proportion tothe pressure or quantity passing through said main. As the valve diskrises and the weight 15 drops the mechanism described above opens thegate 17 to admit a proportional flow from the auxiliary supply, and asthe pressure drops a reverse action takes place closing down theauxiliary flow to the required amount.

An essential feature of the device is that the flow through the mainsupply pipe not only actuates mechanism to automatically admit aquantity of other liquids or gases but. that this flow so controls andregulates said liquids and gases that they will always be in apredetermined ratio to the amount passing through the main pipe and willincrease and decrease in direct proportion to the increase and decreaseof the flow through said main.

Our invention is not restricted to the construction and arrangement ofparts herein shown and described nor to the various details thereof, asthe same may be modified in various particulars without departing fromthe spirit and scope of our invention, one
